These grooves 108 are associated with windows 110 which are intended to receive the ends of the elastic tabs of the insulators forming a rear stop. In addition, these 110 lights make it possible to verify the correct snap on the insulators on the base body.
  • This rear part 106 of the base body also has on its external face different means of fixing the rear connector depending on the nature of this one.
  • Other types of rear connection are also found fixing notches 118. These notches will be used in particular to fix a rear connection of the type which will be described in connection with FIG. 9.
  • the rear part 106 also includes an indexing plate 119 and for immobilizing the base body in rotation in the panel on which the base is mounted when the screen 24 is used.
  • the part rear 106 of the base body has a protruding index 120 which provides a angular location and allows in relation to the coding information of different housing already described to achieve the correct positioning of the insulation with its conductive terminals relative to the base body.
  • This plug body 26 comprises a front part 130 having a cylindrical external shape on which are provided ribs such as 132 and 134 which define coupling keys or compatibility with the base in relation to the grooves 122 and 124 present by the base. On its external lateral face, the plug body also has a circular rib 136 which serves as a stop for the coupling nut as well as the shows Figure 1. Between the annular flange 136 and the ribs 132 and 134, we finds a zone 137 intended to receive the mass spring, not shown, which is used to ensure electrical continuity between the base and the plug when these parts are assembled.
  • this zone is frustoconical.
  • the front periphery of the base body tends to push back the spring by relative to its rest position.
  • the taper causes the radial expansion of the spring, referenced 139 in FIG. 1, which ensures the electrical contact between the spring and the plug body despite the clearance between the plug body and the spring when this one is at rest.
  • the front periphery of the base body is necessarily in electrical contact with the spring 139 due to the taper.
  • the rear part 138 of the plug body 26 is identical to that of the base body already described. Onne will therefore not return to the description thereof. Note, however, that the periphery of this rear part 138 also has a locating index angular 140 whose function is the same as that which has been described in connection with the base body.
  • a specific tool can be used to separate the male insulation or the female insulation of the socket body or the plug body in the event of angular positioning of the insulation relative to the base or plug body by relative to the coding of the connector.
  • the coupling nut 24 has at one of its ends on its circular internal face 142 three threaded sectors 143 equidistant and corresponding to an angle at the center substantially equal to 60 °. These three threaded segments 143 are intended to cooperate with the thread provided on the base body which bears the reference 36 in FIG. 1. On this internal face, there is also finds three identical relief sets each carrying the reference 144, these three sets in relief also corresponding to an angle at the center of the order of 60 ° and being angularly offset from the sector threaded 143.
  • Each raised portion 144 comprises on the one hand a notch 146 intended to snap the nut onto the plug body, a guide sector 147 forming a shoulder is intended to cooperate with the annular rib 136 of the body plug and three tactile and auditory locking notches 148, these notches 148 provide that the locking of the nut on the base has been correctly carried out.
  • the rear connector 37 consists of a half-shell lower 150, upper half-shell 152 and a flange for fixing the cable 154.
  • the two half-shells are joined together by the cooperation of the peripheral belts 156 and 158 and of screws, not shown, engaged in holes 160 and 162.
